Hazard Information

Description

(S)-(-)-Propranolol is the active enantiomer of propranolol, a β-adrenergic receptor antagonist with log K_d values of -8.16, -9.08, and -6.93 for β₁, β₂, and β₃, respectively. It is also a non-specific serotonin receptor antagonist. Propanolol was one of the first β-adrenergic receptor blockers to be widely used in clinical practice for the treatment of hypertension, angina pectoris, and cardiac ischemia.

Chemical Properties

(S)-(-)-1-(Isopropylamino)-3-(1-naphthyloxy)-2-propanol hydrochloride

Uses

active enantiomer, 5-HT1 receptor antagonist

Uses

Antihypertensor;Beta-adrenergic blocking agent

Uses

The S-enantiomer of Propranolol (P831800). β?Adrenergic blocker. Antihypertensive; antianginal; antiarrhythmic (class II).

Biological Activity

More active enantiomer of the β -adrenoceptor antagonist propranolol ((RS)-1-[(1-Methylethyl)amino]-3-(1-naphthalenyloxy)-2-propanol hydrochloride ).

Biochem/physiol Actions

(S)-(?)-Propranolol hydrochloride is biologically active enantiomer. It acts as β1 receptor antagonist in thalamocortical neurons. (S)-(?)-Propranolol hydrochloride elicits its inhibitory function on the β1 adrenoceptor in trigeminovascular pain pathway and serves as a preventive medicine in migraine.

storage

Store at RT

Purification Methods

The (+)-salt is the active isomer which blocks isoprenaline tachycardia and is a -adrenergic blocker. [Leclerc et al. Trends Pharmacol Sci 2 18 1981, Howe & Shanks Nature 210 1336 1966.]
